This invention relates to new and useful improvements in gauges and has particular reierence to gauges for measuring or gauging rivets to determine their number, andY also 'A ormeasuring the thicknessof brake linings and clutchv facings. i n

An object of the invention is to provide a gauge for thepurpose stated and vwhich "is simplein construction being formed from a single piece of material cut and marked with suitable graduatio'ns. Y l 3 Another object is to provide a gauge having recesses of various depths and widths, the recesses being of greatest widths attheir envtianceends to accommodate rivet heads of various diameters, the recesses receiving rivet shanks of various diameters and each recess having graduations associated therewithV and adapted to b e read in connection with the ends of rivets,the heads and shank's'loi which are lof diameters to snugly fit into the recesses, to

give the proper number `for the rivet. V Afurther object is to provide a gaugejforthe purpose and having the characteristics stated and'which includes means for measuring the thickness 'of brake Vlinings and clutch I facings `and which alsoincludes a scale for leo measuring the width of brake'linings.

Other objects and advantageswill become apparent from a consideration of theiollowing description taken in connection with the accompanying drawings wherein a satisfactory'ernbodiment `of the invention `is shown. However, it will be understood that the invention is not limitedto the details disclosed lsince theinvention includesall such modifications as fall within the'scope ofthe appended claims to which reference, must be had fera definition of the limitations of theinvention.

, In the drawings:` Y* f y i 1 Fig.' l is a side elevational view ofthecomplete gauge; and Y Fig. 2 isa top plan or edge view thereef,V

Y lnthe trades, rivetsaredesignated bynumber and each number means a rivet having ya Vgiven diameter and length oit' shank and. a. given diameter ofj head.l lin automobile [brakes Afor example, the friction linings are secured to thebandsands'hoes by rivets and the rivets Ychosen must be ci the proper identifying'number since unless the shanksot f the .rivetsare of the proper diameter they willnot iit throughvthe openingsin the brake bands andshoes. Y Also unless the heads 4ofthe rivets are of the proper diameter theywill'` not iitinto the counter-sinks providedfabout lthe openings in' the brake bands, shoes orliningsf and scoring-lof the brake.drums. may result. l i

Furtheniit will be understoodthat brake bands, shoes and linings are provided `iii "difthe rivets'used must' b'e of the'properjlength since otherwise they-will either not properly secure the bands to the brake shbeswhenthe rivets are too short, orelse theymaybetojo Sult. Y j i According Y is provided whereby the operator'or mechanic to the' present inventicn afgauge' 70 may readily determine' thenu'mber of; a rivet,

it being understood that-rivets identifiedv by a certain number are Vused with brake lining .of known thicknessl and width for each make oi car.' Also, with theV gauge oigthis inven-A tion the operator may. readily determine they width and thickness of brake linings. There'- fore, being ,equipped with this "improved-Q, i

gauge ,he may determine all that is necessary regarding the material for-any particular ]ob. i

. Referring in detail to the :drawingstheimiproved'gauge islshown as lformed from a fiat piece of material, preferably `metal,V and comprisingr a body.v portion 5 having a series of recesses 6, T, 8, 9, 10,11, l2 and 13 cut into y it iromits upper edge. t. 'These recesses are 'of Y theA widths indicated by the markings at their low/erA or inner ends andfcertain of the rei Y l 90 hasian enlarged or wider outer portionindi- `cesses :are deeper than others. Each recess cated ai. 16,117, is, 19,20; airfgeandjaarespec Associated with thefdiEerent-recessesare markings orgraduations crresponding to the',l

designatingcr ,identifyingv numbers .of riv- 'ciated withn it and it is thereby to be4 underL stoodthat-a rivet,"the shank oii which `:fits

60A ferent' thicknesses for'diii'erent'carsand'th'at fsnugly'within and so of the same diameter .10.701

as the width ofthe restrictedportion Vof recessl 6 filling the same, is of the same length as the depthof this recess, and the head of. which is the same' diameter as the'width of the enlarged outer portion V16 of the recess, YVis that rivet identified Yinthe trade asnuml ber" 26. 'A rivet accomplishing the samek thing in therecess'? would be a rivetidentii, 'fied in the trade as number 25.

m The-other recesses gauge rivets according^ 1y. f For "example,v recesses l()l and' 11 will take :a rivet the ldiameter of the shankV of e i wliich"is 9/64ths of an inch. However, the

Y"will accept* rivets the heads of lwhich are outer portions or enlarged portions or enf trance portions/20 and 21 ofthese recesses of ldifferent diameters, it being obvious that therecess V11 in its outer portion' 21 will receive Va rivet the head of which is, of such diameter that it would notbe received in the f outer portion y20 ofthe Vrecess 10. p Therefore, assuming that a rivet shank fits l. l' snugly in the'restricted portiony of the recess 10=but thaty the head Yof the rivet will'not fene ter the enlarged portion of said recess then p the rivet will bev tried in the recess 11 and the shank yandv headV fitting snugly in this recessthegraduationopposite the end of the rivet willfgive its number. VA rivet is shown invplace in therecess 12 and it will be noted that the hea-'d of this rivet lits snugly `within 'the .enlargedportion 22 of the recess while Ythe Vshank fits snugly'within the restricted portion of the same. Since, the end of this Krivet indicatedfat 11i isV vopposite the gradua- -tion"11- itwill be understood that this rivet 'will beidentilied in the trade as a :#:11 rivet,

From the foregoing :description it is be` L lieved' that the operationof the device as a] rivet, gauge will be fully understood. Itis simply necessary tofind the recess which lis of. a. width to snugly take the shankpand head ofthe rivet as regards the diametery of the i same :and that number 'or graduation opposite the end of v-thefrivet will give` the A tradenumber of the' rivet. Y

Y The device is also operative as a brake linifingand,clutch-.facing thickness gauge, it bei ing merelynecessary to insert the edgeof the lining or facing intooneof the recesses and the reading at the inner end ofthe recess will give the ythickness ofthe facing ory lining when the facing or lining fitssnugly in the recess.r A recess 15 of a 55 inch width is y VVprovided in onetransverse edge of .thevgauge this. 'recess'.giving an additional reading as i f -regardsthe thickness vofl a` clutchfacingor Y brake lining, The loweredge of the.V body 75, or thatfedge opposite the edge intoV which the recessesare cut is providediwith graduations in inches and v:fractions thereofwhere-'-V byfthe widthof abrake lining vmay bejdetermined',V f Thus, if a given job calls for' a vfacY ing of-a givenythickness'- andwidththe operator `can easily determine, K whether any will be seen that I 'have provided a gauge vfor given piece of lining is of the proper widthr yand thickness. c j A Y `The foregoing description will, it is .be- `lieved, suffice lto 'make clear the construction andioperation of the improved gauge and itY the purpose stated` which is extremelyvsimple Y Ain construction and which cannot get out of i orderfand which will withstand an yappreciable'amount of-fabuseA Further, it will-be seenzthat the gauge isusefulfor al number of purposes in connection with the applicatie 'ofbrake'linings or clutch facings.
